FSSEELYE,

a citizen of the United States, residing at 'NeW HaVen, in the county of *Ne'w Haven and State of Connecticut, have'i'nve'nted a new and usefullmprovement 1n Lock- Canal following, when taken in connection with the accompai'iylng drawings and the characters of reference marked thereon, to be a, full, clear, and exact descr ption of the same, and which said drawings constitutepart ofthis application, andrepresent, in

without necessarily turning them about. 1 My 1nvent1on fUIthQI'COllSlStS 1n a-mlnlature lock-canal toy having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

ably this waterI-tank2 will be made out'of sheet *mztalbut that isl'not material. Intothis tank 2,I' set a shallow tray 3 substantially conforming to it in size, having, as shown, rounded ends and also preferably made of sheet metal. The saidtray 8 has anOVerJapping flange 4 and formed with a large central opening, 5 rounded. at one end, rectangular at the-other'e'n'd, and outlinedby a vertical wall 6. .The'bottom of the said" tray consists of an upper level 7 anda lower level8, connected by a vertical wall 9 arranged transversely with respect to the length of the tray. As thus constructed the trayf3 contains a continuous channel consisting of two substantially U- shaped'parts merging into each other on the line of thewall One o f these U-shaped parts forms-what fmay becalled the sea level channel l0, and the other the upper level channel 11', The upper level channel 1.1 is widened to form a miniature; lake 12 which may be given the name of Gatun lake. Inte'rposedbetween'the two channels 10 and'11,-.I ljoc'ate two corresponding locks 13 and ll." Eachof'these' locks is furnished with a pair of'short upper-level gates 15' and a pair of longer-'sea-level gates 16. These pairs ,ofgates' are sufliciently separated from each-otherto receive between them toy vessels such as 17, .1'8 and 19. EX- ceptfor differences in length, the gatescorrespond inconstruction, each being fur mg 20w0 rking in vertical sockets 21 ap-' plied to the inner faces'of the vertical channel-walls 6 and if preferred, the sockets 21 may be cast-integral with the walls, .depending upon the construction chosen for the tray 3, 1 One gate of each pair of gates is provided with a 'wicket, so called, con

sisting of a rotarystem 22 furnished at its upper .end with an operating-arm 23 and formed at jlts lower end w1tha.'vert1cal seing ports 25 formed in a reinforcement 26 furnished with corresponding stoplugs 27.

The edges of the gates are also rabbeted as l at 28' so as to be interlocked when closed,

whereby they are made water-tight. When the locks are filled with water from the upper-level or lake channel 11 and then riesofports 24L registering with correspondlocated upon the lower inner cornerof the gate, the other gatejof the same pairbeing opened, there will beanexcess ofwa'ter in" the sea-level channel 10. To prevent an overflow, -thesea-level channel 10' is pro'- vided with oVerflowpor-ts-29 (Fig. '2) which permits the excess to flow into the water tank 2 fromwhich it is pumped back into" the upper-level or lake channel 12 by means" o'fa small'removablepump 30 of the bilge" pump type, or some other device-answer r ing the same purpose. 4

, A miniaturelockecanal toy, constructed as; above described, provides a continuous channel oftwo levels equipped with. two locks which permitgthe miniature ships 17,: 1S and 19 tobe raised. and lowered just as the largest ships are handled in the Panama Canalor any other canal otthe lock type.

Fig. 1 ofthe drawings, shows the vessel 17 in thelock 13 of which .the upper-level gates 15 are closed'and; the sea-level gates 16 are open. The lockw13 may bedesig nated as the Gatun lock. The vessel 18 is: represented in the same figure as having passed through the Gatun lock 13 and into Gratun lake l2'on its way to the,lVIirafiores lock 1% the upper-level gates 15 ofwhich are open, and the sea-level gates; 160i which are closed, and which contains the vessel 19. Supposing the vessel 17 to have just entered the Gatun lock 13, as shown in Fig. 2,,the sea-level gates 16 are then closed and the wicket in one of the upper-level gates 15 is opened, permitting the-lock to gradually be 'filled from the water in theupper-level channel 11. During the filling of the Gratun lock lS, the vessel 17 will slowly be'raised to thelevel' of the water in the upper-level channel 12. The wicket in one of the upperlevel gates 15 willlthen'be closed after which the said upper gates will be *openedto per' mit the vessel 17 to p'assin'to the upper-level channel 11. The upper-level gates 15 are then closed and the wicket of the lower .gates opened topermit the waterin the-lock 13 to flow into the sea-level channel 10, whereby the level of the water in the lock 13 will be reduced to the level of the water in the'sea-level channel 10. .As'to the ves sel 19'shown'in Fig. 1,.itmay besupposed to have just entered theMiraflores-lock- 14 previously filled to the level of the upperlevel canal 11 by the closing of the lower level gates 16 the wicket Of.WlLi Cl1 has,-e0'lhearse, been 'elosedf "Theupper gates 15 are now closed, their wicket 22 having been closed preparatory to the open-ing of the gates; Th'e' Wicket QQ'of the lower gates is ,now opened to permit the gradual subsi- "denceofth'e water in the lock to the level of the sea-level channel 10 whereby the vessel is allowed'to descend to the level ofthe' said lowerichannel,after which the lower gates 16 are opened to permit the vessel to proceed into the se-a level channel. vThis cycle As already stated, the form'of the tank land-tray may. be changedand the details .or the-lock gates altered But inany form ,which my improved toy may assume, the ,canal will be continuous and the locks .arranged so that each vessel may be deployed through the canal locks by constantly going ahead, never turning about.

Although ther principle of raising and loweringships by means of locks is in itself simple, it is not generally understood even by adults. of a lock canal is perfectly and clearly dem- .onstrated by. my improved toy which will However, the whole operation arove a source of interest icomment-andrinl 7.
